Log rhythm question help

Consider the following ‘proof’ where for convenience we have numbered each
step.
1. Clearly ( 1)
2
= 1, and so
2. upon taking logarithms we have that ln( 1)
3. Using one of the logarithm rules we have that 2 ln( 1) = 0,
4. or upon division by 2, that ln( 1) = 0.
5. Therefore el
n( 1)
= e0

,
6. which simplifies to 1 = 1.
The conclusion of the ‘proof’ is clearly false, so explain exactly at what
step(s) things went wrong.

So basically I got for the answer: log(-1)(1)=2

I just want to know if my answer is right. I would really appreciate some helps thanks!
